I can't label him a full choker since he does have a FMVP outplaying the best player in the world in the series, but since that 2014 run, his playoff history has been spotty. Let's see:
2015, high expectations for the Spurs to finally go to back-to-back. Kawhi has emerged as the face of the club. Best player in the world label thrown around a bit after a stellar game 3. Outplayed by Matt Barnes in Game 7, and had a terrible final 3 games to end the series.
2016. yeah LMA is coming to town! le favorites at the beginning of the season, even with the emergence of Golden State. Spurs absolutely stomp the out of the Thunder in Game 1 of the WCSF. Game 2 the Spurs lose by 1. Leonard? 14 points on 7-18 shooting. In the closeout game 6, he went 9-23 for 22 points. He was also 7-19 in a critical game 4 loss.
2017 is obviously an incomplete.
2018, ed out from the post-season. Insight into his mental for ude?
2019. Remains to be seen, and he's been very good thus far, but the Raps haven't played any real teams till now, and his performance tonight was mediocre. And he salvaged a 16-39 choke job in game 7 against Philly with, let's be honest, a lucky shot.
I'm not saying he isn't a championship centerpiece, he is. But he definitely needs a big balls player as his wingman to hit big shots and turn in efficient performances when he reverts to that player that was outplayed by Matt Barnes.
